I have been using a licensed verison of Mach 3 for about 2 yr.
My Vista box died, so I found an XP machine with a parallel port.
Loaded the software, ran the driver.exe....all is fine
When I powerup I hear 2 or 3 spurious pulses to the motors, so I know the steppers are fine.
I have set the ports and pins.
Set up estop again.
copied the XML file into the mach 3 directory.
I HAVE NO STEPPERS MOVEMENT
parallel port is the default address
I can use JOG, the DRO's move , but no stepper pulses.
NEED SOME ADVICE...
keep in mind , all I did was unplug my parallel port and plug it into the new machine, after loading software....dont have any stepper hardware issues.

forgot to mention that all 3 axis are enabled

Double check in device manager that the port address is correct.

You could test directly at the computers port with a volt meter on the Dir pins to see if the state changes when youjog one way then the other.

I found I had to set the port assignment, under ports and pins.....
I would think this would be saved in the XML file, but apparently ther is some issue.
It is running again
